Preheat oven to 350 degrees F. Place pistachios on a baking sheet and into the oven to roast for 8 minutes. Set aside. Grease a loaf pan with oil then line the middle with parchment paper. It will make it easier to remove from the pan without it coming apart.
Pour batter into bread pan and top with the rest of the pistachios. Then place in the oven to bake for 50- 60 minutes, until toothpick comes out clean from the middle. Let rest for 5 minutes before removing from pan.
